Power Line Filter Modules
Power line filters are very important components in the power circuits. They are used to prevent interference from affecting other circuits on the power supply panel or within a component. The power line filter is generally divided into a high-frequency filter and a low-frequency filter. The filter module of the 3EQ1 application field and working principle belongs to the low-frequency filter.
3EQ1 Application Field
3EQ1 filter modules are used in AC-DC converters, DC-DC converters, switched power supplies, and others. They are particularly suitable for Pulse Width Modulation (PWM) type of power supplies and high frequency AC-DC converters. The 3EQ1 filter modules have a wide range of operating frequencies from 45 kHz to 500 kHz. The 3EQ1 filter modules are designed for application of low-frequency suppression of both differential-mode and common-mode noise. The 3EQ1 filter module also provides good ripple rejection over an extensive frequency range.
3EQ1 Working Principle
The 3EQ1 filter module is composed of a three-section inductance filter, in which each section is an inductor and capacitor combination. The 3EQ1 module has three sections, each with a single series inductor and two parallel capacitors. The inductor works together with the capacitor to form an LC resonant network, therefore, the 3EQ1 module works as the resonant LC filter. It has the function of attenuating the high-frequency signals generated by the switching device. The signal passing through the filter is low-pass filtered by the LC circuit. At the same time, the LC circuit also blocks the EMI (electromagnetic interference) on the power supply line.
Conclusion
3EQ1 filter modules are used in a wide variety of power supply systems, from AC-DC and DC-DC converters to switched power supplies, to filter out unwanted high-frequency noise. The 3EQ1 filter module is composed of an inductor-capacitor network, which filters out high frequency signals while simultaneously blocking EMI. The 3EQ1 filter module is an essential component in maintaining a regulated power supply system.
